(iharles; Q nethweiler, i waukee, mimostenavddwhiteqempahnmilaaaheertthY Applicati n Ap l in, 1 5a sonnet. meta s ohms (otscaeirsi My inventionrelates to adjustabie bearings and more particularly to a type ofbearingadaptable for the: axis mounting of a, telescope or the like,

The object ofmy invention is to provide a, bear:

that permits ease, in mounting a. telescope specifi d nd ve. t ng thetelesehie- 1mins bet een beari gs whic are e, l ed in a manner p rm tsheme A- line the s ope whi e assembl n and tainin the sc pe in the poper position. The ons ruct on oi the d ce s such that it w ll permitadjustment to correct any variations and displacements that; may oeeurduring transportation of the asse'mbled device and the handling of it.

Qther nd further ebieete eiwi become more ehhare t as descrip r ceedsand when taken in conjunction with the drawing in which Figure 1 is afragmentary cross-sectional view of the bearing inserted into atelescope mounting and illustrating the manner in which the axismounting of the scope is adjustably sup ported.

Figure 2 is a side view of the device showing the telescope in phantomand means for vertical adjustment of the axis mounting in crosssection.

Similar characters of reference indicate corresponding parts throughoutthe several views and referring now to the same, the illustration showsa telescope standard comprising two upwardly disposed members l0 and I0integrally mounted on a base plate shown as Ii which forms a standardmounting or attachment to a tripod or the like.

The member ID is shownprovided with a vertical axis adjustment in the form of a horizontallydisposed slot 33, and the edges of the member I!) at the opening of theslot 33 are provided with an upper member 34 extending outwardtherefrom, and a lower member 35 also extending outward therefrom.

y The upper member 34 has a tubular insert or bushing 36 threaded on itsouter peripheral surface and threadedly engaging the member 34. whilethe lower member 35 is provided with a threaded aperture 31 into which ascrew 38 extending through the bushing 36 is threadedly inserted. Thelower end 39 of the bushing 36 contacts the lower face 40 of the slot33, therebypro viding a means of forcing the members Stand 35 apart,while the screw 38 will permit drawing the 40. Obviously, thecombination of the screw 38 and the bushing 36 forms a locking means forkeeping the slot in a fixed position.

From the foregoing description it is manifest that the bearing assemblyas illustrated and described will permit ease of assembling the axismounting 2| into the stand comprising the vertical members In and II),which are integrally formed and supported at the lower end by the baseH, inasmuch as the threaded apertures in the support member I2 arelarger than the shaft member 20, and will permit engagement of theadjustable bearing housing M from theoutside. The housing l4 may beretained in a fixed position after assembly by the'plate l6 which alsoseals the bearing from dust and foreign matter. Likewise, the tangentclamp 24 may be retained in frictional engagement with the axis mounting2| by means of the lock nut 26 and the cupped spring washer 28. Thevertical adjustment of the entire device is accomplished by means of'thehorizontal slot 33 within the member Ii! which is spread apart or drawntogether by means of the screw 38 and the bushing 36.

In the chosen embodiments of my invention there are many features notheretofore revealed or disclosed in the prior patent art and while Ihave shown a particular arrangement of the component parts constitutingmy invention, I am fully cognizant of the fact that many changes in theform and configuration of the various component parts may be madewithout efiecting'their cperativeness, and I reserve the right to makesuch changes in the form and contour as I'may deem necessary withoutdeparting from the spirit of my invention or the scope of the appendedclaims.

Having thus described my invention, what I claim and desire to secure byLetters Patent in the United States is: V

1. An axially adjustable bearing assembly comprising, a frame having athreaded aperture therein, a generally tubular housing thr'eadablymounted in said aperture and having centrally bored wall at one endthereof to receive the end of a shaft, a bearing assembly mounted withinsaid housing against the inside of said ,wa1l. a cover plate threadablymounted in the" open end of said housing and operative to fix saidbearing assembly with respect to the housing, and a lock ring threadablymounted on theexterior ofsaid housing and abutting said frame to fix thehousing with respect to the frame. I

2. The combination with an instrument frame having two generallyvertical standards, each provided with bearing assemblies supporting theends of telescope shaft, of means for adjusting one of said bearingassemblies vertically and comprising, a slot in one of said standardstransverse a generally vertical plane including the axis of said shaftand extending through one of the standards a sufiicient distance so thatsaid one standard is integral on only one side of said plane, screwmeans on the other side of said plane for moving the portions of saidone standard on opposite sides of said slot towards or away from eachother.

3. An instrument telescope shaft bearing mounting, comprising, a frameincluding a base and a pair of vertical standards each of which includesa threaded aperture in general axial alinement with the threadedaperture in the other standard, a generally tubular housing threadedlymounted in each of said apertures and having a centrally bored wall atone end thereof, a bearing assembly mounted within each of saidhousings, a sealing plate threadedly mounted inside of each housingremote from the bored end wall of the housing and being operative to acton the bearing assembly to fix the bearing assembly with respect to thehousing, a telescope shaft having each end supported in one of thebearings and provided with shoulders engaging with the outer face ofsaid bored wall of each housing so the shaft may be adjusted axiallywhen the housings are rotated. 1 4 The combination according to claim 3including a lock ring threadedly mounted on the exterior of each housingand abutting the frame to hold each housing in its adjusted position,

5, Apparatus according to claim 3 and including means for adjusting'oneof the bearing housings vertically, comprising, a slot through one ofthe standards generally transverse a vertical plan e including the axisof said shaft and extending through the standard a sufiicient distanceto leave but a portion of the standard on only one side of said planeintegral, and means for moving the portions of the standard on oppositesides of said slot to and from each other and for retaining saidstandard portions in their adjusted relationship.
